The Swendsen-Wang dynamics is a Markov chain time-honored through physicists to pattern from the Boltzmann-Gibbs distribution of the Ising version. Cooper, Dyer, Frieze and Rue proved that at the whole graph Kn the blending time of the chain is at such a lot O( O n) for all non-critical temperatures. during this paper the authors express that the blending time is Q (1) in excessive temperatures, Q (log n) in low temperatures and Q (n 1/4) at criticality. in addition they offer an top certain of O(log n) for Swendsen-Wang dynamics for the q-state ferromagnetic Potts version on any tree of n vertices

Note that |Xt | and the original magnetization chain has the same distribution. 1 gives the required upper bound and concludes the proof. 1. 3. [Crossing and overshoot] Let Xt and Yt be two SW magnetizad tion chains with X0 ≥ n3/4 and Y0 = π. Put T = min t : Xt , Yt ∈ [A−1 n3/4 , An3/4 ] and |Xt − Yt | ≤ hn5/8 , for some constant h > 0 and large constant A. Then we can choose positive constants h, q, K depending only on A such that P(T ≤ Kn1/4 ) ≥ q . 4. [Local CLT] For any constants A > 1 and h > 0, there exist constants δ = δ(A, h) > 0 and k = k(A, h) ∈ N such that for any x0 ∈ [A−1 n3/4 , An3/4 ] and any x ∈ n + 2Z with |x − x0 | ≤ hn5/8 , we have P(Xk = x|X0 = x0 ) ≥ δn−5/8 .

34) is o(1). 34). Since EX = mP(|C(v)| ≥ ) it suffices to bound from above P(|C(v)| ≥ ). Recall that |C(v)| is the hitting time of the process {Yt } at 0. 16. Let τ = mint {Wt = 0} be the hitting time of Wt at 0, then it is clear that we can couple Wt and Yt such that |C(v)| ≤ τ .
